What Is the Urban Tap in Pittsburgh PA
The urban tap in Pittsburgh PA refers to the municipal drinking water system managed by the Pittsburgh Water and Sewer Authority (PWSA), which serves the city and surrounding areas. The system draws raw water from the Allegheny River and treats it at multiple plants before distributing it through an extensive network of pipes and storage reservoirs. PWSA operates under a consent order with the Pennsylvania Department of Environmental Protection, requiring upgrades to address aging infrastructure and lead service lines. The utility is regulated by the Pennsylvania Public Utility Commission and must comply with federal Safe Drinking Water Act standards enforced by the U.S. Environmental Protection Agency. For an overview of the Safe Drinking Water Act framework, see the EPA's Drinking Water Requirements for States and Public Water Systems page here.
Pittsburgh's urban tap system includes the Highland Park, Aspinwall, and Millvale treatment facilities, which together process billions of gallons annually. The PWSA maintains thousands of miles of water mains, with ongoing capital improvement projects focused on lead pipe replacement and transmission main rehabilitation. In recent years, the utility has implemented advanced monitoring and corrosion control treatment to reduce lead exposure in homes served by lead service lines. Customers can access annual water quality reports, also known as Consumer Confidence Reports, through the PWSA website and the EPA's Drinking Water Watch portal here.
Water Quality and Contaminants in Pittsburgh's Urban Tap
Lead and Copper Rule Compliance
Pittsburgh's urban tap has faced scrutiny over lead levels, especially after the city's switch from chlorine to chloramine disinfection in the early 2000s, which initially increased lead release from pipes. The PWSA has since installed orthophosphate corrosion control and accelerated lead service line replacement to bring levels into compliance with the federal Lead and Copper Rule. The EPA sets an action level of 15 parts per billion for lead at the tap, and PWSA's sampling data is publicly reported in its annual Consumer Confidence Report. The agency also posts violations and enforcement actions on the EPA's Enforcement and Compliance History Online system here.
Other Regulated Contaminants
Beyond lead, Pittsburgh's urban tap is tested for a range of regulated contaminants, including disinfection byproducts, turbidity, nitrates, and volatile organic compounds. The PWSA's treatment processes target these contaminants to meet Maximum Contaminant Levels set by the EPA. The utility also monitors for unregulated contaminants through the Unregulated Contaminant Monitoring Rule, which helps inform future regulatory decisions. Data from these tests are available in the PWSA's annual water quality reports and through the EPA's Safe Drinking Water Information System here.

Capital Projects and Funding
The PWSA has undertaken a multi-year capital improvement program to replace lead service lines, repair water mains, and upgrade treatment facilities. Funding sources include municipal bonds, state revolving fund loans, and rate increases approved by the Pennsylvania Public Utility Commission. The utility's rate structure is designed to recover costs while maintaining affordability for residential customers. In addition to lead line replacement, projects include tunnel rehabilitation, storage tank upgrades, and smart metering pilots to improve leak detection and system efficiency.
